tion, in connection with the uot-oinpnnyiugr drawings. is it s 'uoiticiition, like cl'uirzu'trrs on the d outings representing like ports.

This invention relates to :i composit building structure especially designed and :u'lnpted among other uses to he .eniployed us the root. walls and floors of mills :ind other buildings.

The invention has for its object lo provide it reiu'tmced concrete construction which is simple, inexpensive, durable and highly et- Iiciont.

The invention is herein shown as embodied in :1 root to which it. is }1ttltlL3Itl:-ll'l nppli' cable. with H, corrugated Inember. preferably a To this end the roof is irovided 9 sheet. of metal and preferably (*orrugnlml :isbestos protected nit-till, said member being;

composed ot n plurality of corrugated sheets which are scoured to the root purlins in a novel manner as will he described. The concrete is luid upon the corrugated incur her and is provided with a. metal rein't'orc( .ment, which is inot-luinicully bonded to the root. purlin as will he described. Provision is also made For supporting the metal rein- "orcement above the roof purlins as will be described.

These and other features of this invention will be pointed out in the claims at the end of this specification.

Figure 1 represents a uutlioiont portion of a root construction embodying this invention to enable it to be understood. Fig. 2- a section on on enlarged scale 2--2 Fig. t. Fig. 3, :1. section 3----3 Fig. 1 with the concrete Fig. 4, :i detail of the bridge or the metal reinforcement, and l igs. details to be reterrcd to.

Referring to the drawing, a, I), represent two adjacent sheets of corrugated material, preferably asbestos protected metal, which form port o the corrugated member ol the. roof.construction. The sheets (L. t). have on the lino in position. support tor 5 and 6,

their :ulim-wtt ends overlapped nud sup-- on the line ported by :1 metal roof purlin o, of known construction and usually :1 channel. iron hev int; :1 [hinge (I :it its upper end, which is engaged on its upper and lower surfaces by u. purlin clip 0, whose substuntiully tint upper part or member has secured to it; :i

The base llzinge 10 of the bridge piece serves as 21 washer against. which the bend ot the rivet beers. The bridge piece thus hos its lower portion located. within, :1. valley t l ot the corrugated sheet and is provided with an upright portion or memher, which is nuule of .sutlicient. length to extend above the highest part of tho corrugated sheets. end is slotted :it its upper end to form lingers l5, [(3, one of which '15 16, is bent ttt nu angle to the other to form a. V or crotch for the reception of n reinforcing rod 17, which extends hmgitudinully of the corrugnted sheets, and which serves to bind or secure :1 transverse reinforcing rod t8 in the slot it.) formed in the upper end of the brit'lgc between the fingers as elenrly represented in igs. Z uud t. The longi tudiuzil reint'ow i no; rod lT are inclined down tt'Utll the bridge toward the corrugated shoot and are .ield in the valley by retaining clips :10, which hook over the rod l7,- und have n base flange 21 which is bolted, riveted or otherwise secured to the corru- {Jutcd sheet.

The bridge pieces 5 may he loc'tited in each valley of the corrugated sheet but by menus of the cross rod lb supported by the bridge pieces. the hitter run be separated by one or more rollers, :15 the cross rod serves us an elevated support F r the tension rods 17 of the interiuwliutr rollers :15 clearly li o I construction.

in Fig. l, which serves to reduce the cost of I The tension rods 17 located in thcgilone of the valleys may be connected together between the bridge pieces in the some valley by cross Wires 25, which may he twisted around the tension rods as shown in Fi l. to mechanically connect the longn tudinui and transverse rods of the metai reinforcement. After the motel reinforce meni; has been secured in place on the corrugcted sheets, in which it is held in fixed position by the ramming clips 20, the con crcte 26 is laid thereon to the desired thickness and when set, said concrete layer may have applied to it, aprotective layer 27 of shy-suitable materiel such as asphalt and gravel. I

I have herein represented the invent-ion es embodied in the roof of as building, but it not desired to limit the irniention in this respect as the some construction may be used forthe veils and doors of the huiiding.
